(Cl.206-43) The invention relates to receptacles for sterilization ofinjection syringes with accessories and for keeping of such instrumentsin sterilized condition. More particularly the invention relates toreceptacles having an opening, adapted to be closed by a cover, and aholder for the syringe.

The'invention has for its principal object to provide a receptacle ofthe kind referred to in such a manner that the syringe upon removal ofthe cover is automatically moved from its normal position, in which itis enclosed by the receptacle and immersed in the sterilization liquid,to a service position, in which the syringe is readily accessible by theuser or operator.

To this and other ends the invention resides in certain improvementshereinafter described with reference to accompanying drawingillustrating an embodiment of the invention.

In the drawing, Fig. 1 is a side elevation of the receptacle closed bythe cover. Fig. 2 is a vertical 7 section of the receptacle on line11-11 of Fig. 1. Fig. 3 is the same section but with the cover removedand the holder with the injection syringe in service position. Fig. 4 isa plan view of the cover. Fig. 5 is a horizontal section on line VV ofFig. 2, the injection syringe being removed, and Fig. 6 is a view fromabove of the receptacle with both the cover and syringe removed.

The embodiment disclosed by way of illustration comprises a receptacle Iin the form of a standing cylinder the upper end of which is open andadapted to be closed by means of a cover 2. In closed position, thecover tightly bears on a conical surface 3 (Fig. 3) of the receptacle.The cover on diametrically opposite sides is provided with downwardlyprojecting 1ugs 4 with recesses 5 adapted to engage with an inclinedsurface 6 on the under side of a flange I provided on the outer side ofthe receptacle I. On diametrically opposite sides portions of the flangeI are cut away whereby notches or recesses 8 are formed through whichthe lower ends of the lugs 4 may be moved when the cover is to be placedon or removed from the receptacle. By a slight rotation of the cover thelugs 4 are engaged with or disengaged from the flanges I. By thefriction between the lugs 4 and the surfaces 6 as well as between theinside of the cover and the conical surface 3 the cover will be retainedin tightened position without any additional locking device.

In Figs. 2 and 3 an injection syringe is shown in place in thereceptacle. The construction of this syringe may, of course, vary.According to the drawing it comprises a glass cylinder 8I, a piston 9. apiston rod III, a handle formed by a button II for the operation of thepiston rod, a nozzle or outlet I2, a socket I3, to which the cylinder 8|is attached, and a cover I4 with a hole for the piston rod, said coverIII being removably'iastened to the cylinder. The cover I4 is providedwith a flange I5 by means of which the syringe can rest upon a holder IIfor the parts to be sterilized. This holder II according to the drawinghas the shape of a cylinder or socket which is substantially so-axialwith the cylindrical receptacle I. The socket I1 is provided with abottom I6, and through holes the inside of the socket communicates withthe receptacle I. Thus, there is a central hole I8 in the bottom I6 ofthe socket, and in the wall of the socket two pairs of holes I9, 20 areprovided at different heights. The pair of holes I9 is shown in Fig. 5.To the outer side of the socket II an annular disc 2| is attached belowthe holes I9, 20, a narrow intermediate space 22 being left between thedisc and the inner side of the receptacle I The disc 2| together withthe portion IIa of the socket or receptacle I'I located beneath the discforms the piston of a liquid brake or dashpot the cylinder of which isformed by the receptacle I. To the under side of the disc 2| there isattached one end of a helical spring 23 the other end of which rests onthe bottom of the receptacle I. The spring 23 is a compression springand tends to move the socket I! to the position of Fig. 3. The holder orsocket I'I above the upper pair of holes 20 carries two plates 24 with anumber of holes 25 arranged concentrically about the socket. These holes25 are intended to form seats for syringe needles 26 with socket-shapedmouthpieces 21, by means of which the needles, formed by pointed fiinetubes, may be detachably connected to the outlet I2 of the syringe as iswell known.

In order to prevent unintentional displacement of the holder I'I beyondthe service position, shown by Fig. 3, a stop member 21 is attached tothe inside of the receptacle I. In said position of the holder the outerholder plate 24 will engage with this stop member. In the edges of bothplates 24 notches 28 (Fig. 6) are provided, and these notches enable theremoval of the holder after the latter has been rotated until theprojection 21' registers with the notches 28.

When the receptacle I is to be filled with sterilizing liquid thesyringe is first inserted into the holder so that its flange I5 rests onthe upper edge of the holder. During the filling operation the syringeand holder are held depressed in the receptacle against the action ofthe spring 23 by exerting a pressure on the button II by a finger of theoperator. The sterilizing liquid is filled until it reaches the vicinityof the upper edge of the receptacle and hence covers practically thewhole syringe. Through the hole for the piston rod ill in the cover [4the liquid also will penetrate into the cylinder 8| above the piston sothat the interior of the syringe also is sterilized. The receptacle isclosed by means of the cover 2 whereupon the enclosed syringe andneedles therefore carried by the holder plates for the most part orwholly are immersed in the sterilizing liquid as indicated by Fig. 2. Inthis normal or enclosed position the button I l of the syringe is forcedagainst the inside of the cover 2 by the spring 23 so that the syringeis held in position in the receptacle. When the syringe is to be used,the cover 2 is removed and as a result the socketshaped holder I! withsyringe and needles therefore is moved by the spring 23 out through theopening of the receptacle to the service position. of Fig. 3 in whichthe syringe as well as needles are easily accessible. This upwardmovement of the holder and parts carried thereby is damped by thedashpot action of the parts 1, Ha, 2 l, and the sterilizing liquid inthis movement flows down through the hole l8 and the slight intermediatespace 22 between the inside of the receptacle I and the plate 2|. As theholder with the syringe is pushed outward, the level of liquid in thereceptacle l is lowered so that any risk of spilling the sterilizingliquid after the removal of the cover 2 is'reduced. During thedisplacement of the holder H, the plates 24 and, possibly, also the disc2| will constitute guiding members for the holder.

The design of the details may be varied in many respects withoutdeparting from the spirit ,of the invention. For instance, it is notnecessary to give the receptacle 1 and the holder I! a cylindrical form,but they may have any other suitable shape, such as oval or rectangularin cross-section. The securing device for the cover 2 may also be ofanother character than the one above described.

What we claim is:

1. In a container for an injection syringe, an

elongated receptacle closed at one end and open at the other, a hollowsocket for the reception of the syringe, said socket being ofsubstantially smaller diameter than said receptacle and beinglongitudinally displaceable within the receptacle, resilient means fordisplacing said socket so that a portion thereof projects outwardlythrough the open end of said receptacle, a plurality of longitudinallyspaced plates extending laterally outwardly from said'socket and havingouter edges contacting the inner side 'of said receptacle for locatingand guiding the socket within the receptacle, openings formed in atleast one of said plates providing seats for holding a plurality ofsyringe needles, and a removable cover for closing said open end andretaining said socket in retracted position.

2. A sterilizer for an injection syringe comprismg an elongatedreceptacle open at one end and adapted to receive sterilizing fluidtherein, a socket member longitudinally displaceable within saidreceptacle and adapted to receive the body of a syringe, the socketmember being apertured to permit flow of sterilizing fluid between thereceptacle and socket member, spaced guides carried by said socketmember adjacent the syringe receiving end thereof, said guides extendlngoutwardly from said socket member and cooperatively associated with theinner wall of the receptacle for guiding said socket member therein,said guides having spaced aligned apertures vfor the reception ofsyringe needles, additional guiding means spaced inwardly from saidspaced guides and extending laterall from said socket member andcontacting the inner wall of said receptacle, resilient means positionedbetween said last mentioned guiding means and the bottom of thereceptacle for urging the socket outwardly, means for limiting theoutward move ment of the socket, and a removable cover for closing theopen end of the receptacle and retaining said socket in retractedposition below the level of fluid therein.
